 Data Supplier for the Users Currently Logged OnLocate this document in the navigation structure

The number of users logged on is to be displayed for each SAP instance. All of the questions asked in the checklist for implementation are now answered using the example. The answers are italicized.

  1. What information does a user require to monitor and administer your component? You also need to implicitly decide what monitoring and administering your component means:
    • Does the monitoring include one or more performance values?
    • Does it include the operator waiting for particular messages to appear?
    • Does it include a combination of these two possibilities?


    Only the number of users logged on is reported for each instance. This is therefore a performance value.

  2. How can the information be collected reliably and precisely? Do you have a function module or a report that collects the required information? Can you build this function module or report into your data supplier? Does your component contain the necessary instrument to collect the required data?


    The function module TH_USER_LISTdetermines the number of users for each instance.

  3. How can the user react to problems (alerts)? Do you have an "analysis method" - a transaction, a report, or an external operating system command - with which the user can obtain additionally required information or take the required action to correct the problem?


    Transaction AL08, which displays the number of users currently logged on, is suitable as an analysis method.

  4. Do you have a tool that can automatically react to an alert (auto-reaction method)? Or is there a standard action that is to be taken when an alert occurs (such as the informing of an administrator or the sending of a mail to a call center)?


    Alerts are not to be traced further. It is therefore not necessary to define an auto-reaction.
